PAPSS2 and thyroid cancer: Li et al. found that the differentially expressed GGT6 gene could be one of the key genes in metabolism related prognostic model of thyroid cancer in thyroid cancer tissues by differential expression analysis, Cox regression and LASSO analysis. Together with AWAT2, ENTPD1, PAPSS2, CYP26A, ACY3, and PLA2G10 metabolism related genes, GGT6 gene constitutes a 7‐gene prognostic model, which can be used as an independent predictor to effectively predict the prognosis of TC in thyroid cancer as well as to provide guidance for clinical treatment [67].
